In recent years, there has been an increase in the incidence of dental wear; thus, an early diagnosis is important. Conventional methods of diagnosis are based primarily on the visual abilities of the dentist, and therefore the use of new technologies for the detection of dental wear may be very useful. The aim of the study was to analyze the sensitivity and specificity of the intraoral scanner for measuring dental wear, as well as to evaluate patients’ satisfaction with the use of the scanner. The study was conducted with 46 volunteers who underwent three intraoral analyses: a first baseline scanning, a second scanning after 6 months and a final scanning after one year performed by four operators divided into two groups. One of the operators performed the visual analysis of dental wear, and the other performed the analysis using the intraoral scanner 3M™ True Definition intraoral scanner (ESPE, Seefeld, Germany). The data obtained from the intraoral scanner showed levels of specificity and sensitivity that enable the intraoral scanner to be used as a diagnostic tool in the assessment of tooth wear. The participants also showed a high degree of satisfaction with the scanner as a communication tool.

Se realizó un estudio descriptivo-exploratorio con una muestra de 22 profesores de odontología de la Universidad Europea con destacada trayectoria en simulación. Se integró una comunidad de prácticas de aprendizaje colaborativo con tres simuladores que combinaban interfaces hápticas y de realidad virtual, y se aplicó un cuestionario postexperimental para evaluar la acogida docente de los Simodont-desarrollados por Moog y Academic Centric for Dentistry Amsterdam, ACTA-, dispuestos para ser introducidos en la docencia de la titulación. Para el análisis de datos se utilizó un software SPSS V.21.0 y estadígrafos de media, desviación típica y correlación. Se elaboraron tablas, aplicando pruebas de Kolmogorov-Smírnov y de Kruskal-Wallis, con un nivel de significación de 95%. Se obtuvo como resultados que las aportaciones educativas de Simodont superaban las prestaciones técnicas. Se describió una relación inversa entre las variables edad y facilidad de manejo del simulador. Se evidenció que el manejo de la tecnología de vanguardia decrece a medida que aumenta la edad de los docentes, lo que indicó la necesidad de formar al profesorado en el manejo de la tecnología y en la introducción de métodos didácticos innovadores para el mejor aprovechamiento de las oportunidades básicas y adicionales que ofrece el simulador.

Objectives: The objective of this cross-sectional study was to evaluate the vertical bone gain achieved after the sinus lift procedure with beta-tricalcium phosphate (β-TCP) used as a bone substitute and simultaneous implant placement. Methods: One hundred and twenty-eight sinus lift procedures (utilizing a synthetic ceramic containing 99.9% tricalcium phosphate as a bone substitute) and simultaneous implant placements were performed on 119 patients. The lateral window approach surgical protocol for maxillary sinus lift was performed on the patients. The implants were evaluated using cone-beam computed tomography (CBCT) at 6 months following placement. The vertical bone gain was considered a primary variable, while implant length, diameter, and location were considered secondary variables. Results: The ANOVA results showed no statistical difference in vertical bone gain with implant parameters like implant length, width, and position. Pearsons correlation revealed a statistically significant positive correlation with vertical bone gain and implant length and diameter. A further multivariate linear regression analysis was performed and it observed statistically significant associations between the variables in the study after adjusting for confounding factors. Conclusions: This study concluded that there was vertical bone gain with the usage of β-TCP in maxillary sinus lift surgical procedure with immediate implant placement and that implant variables like length and diameter had a significant influence on the average bone gain values. The implant position did not have a statistically significant influence but there was considerable variation in the bone gain between first, second premolar, and molar regions.

Background Recent years have seen an increase in the use of social media, by the healthcare sector, including dentistry. Indeed, social media may now be important communication tools for dental practices and patients. This work analyzes the influence of patient (male and female) use of dental practice social media on their decision to change practice. The results also provide insight into the factors patients considered important when choosing a dental practice. Methods This study was approved by the Ethics Committee of the Universidad Europea de Madrid (No. CIPI/22.022). Using a web-based questionnaire, a cross-sectional study was undertaken involving a Spanish population that made use of dental services. The questionnaire consisted of four parts covering provision of informed consent, the collection of sociodemographic data, patient use of dental practice social media, and the factors considered important when changing dental practice. Results All participants gave their informed consent regarding inclusion. No compensation was provided for participation. 588 people responded to the questionnaire, of whom 503 were eligible for inclusion. Most respondents were female (312/503; 62%). Most (151/503; 30%) last changed dental practice during the previous 2–5 years. 208/503 (41.4%) indicated that they had visited dental practice social media. 118/503 (23.5%) indicated that they had made use of such the last time they changed dental practice; 102 of these 118 (85.6%) reported their experience to have influenced their decision to change. Respondents who had changed practice in the last 5 years had interacted with dental practice social media more than those who changed over 11 years ago (p < .05), and those who changed practice in the present/past year were more influenced by these media (p < .05). The factor considered most important was 'Facilities and technology'. No gender-based differences were seen for any measured variable (p < .05). Conclusions Different factors affect the selection of a new dental practice, but respondents who changed practice in the last few years were more likely to have made use of dental practice social media, which, for some, influenced their final decision to change. Dental practices might do well to consider using social media as communication and marketing tools.

Resumen-Se diseñó una metodología estandarizada para integrar curricularmente un laboratorio de Simulación Digital Avanzada (Laboratorio Inteligente), con simuladores complejos SIMODONT -7 unidades-, vinculados a servidor y ordenador DELL (19")-Teach Station-, acoplado, a su vez, a proyector interactivo Epson EB 585Wi -para magnificar en vídeo streaming las prácticas digitales y hápticas sobre modelos virtuales en tercera dimensión-. Con base en el método de investigación-acción para estudiar, a profundidad, la validez científica de la intervención en los programas de las asignaturas y el empleo de modelos teóricos de integración de las TIC, se diseñó y aplicó la intervención educativa y se evaluó cuantitativa y cualitativamente, obteniendo como resultado un cambio de paradigma extensible a las prácticas tradicionales de la titulación y un modelo didáctico aplicable a otros entornos académicos en los que se hayan insertado o se pretenda introducir simuladores odontológicos con prestaciones virtuales similares, además de constituir un referente para el cambio y la mejora de los escenarios tradicionales de simulación clínica.
